DIE ADJUSTER OR FASTENER.

SPECIFICATION forming part of Letters Patent No. 647,367, dated April10, 1900.

Application filed March 31, 1899.

To all whom it may concern:

Be it known that LGEORGE W. BLAKESLEE, a citizen of the United States,and a resident of Plantsville, in-the county of Hartford and State ofConnecticut, have invented certain novel, useful, and valuableImprovements in Die Adjusters or Fasteners, which I desire to secure byUnited States Letters Patent; that my knowledge of these improvements Iwish, in order to cover same by Letters Patent, to publicly divulge inaccordance with law, and that therefore the following and the annexeddrawings and characters of reference thereon are provided for inspectionand by me hereby declared to constitute, when taken together, aspecification of the said improvements, replete, explicit, and exact,sufficiently to enable any person versed in the art to which myinvention appertains to perform the same.

My invention relates to die adjusters or fasteners, has for its objectto provide a die adjuster or fastener which shall be inexpensive,simple, effective, and applicable to orworking presses, and consists inwhat will dinary drop forging machines and metalbe hereinafter describedand claimed.

The accompanyingdrawings,in which similar marks of reference denote likeparts throughout all of the figures, represent, in-

Figure 1, a view in side elevation of a device embodying my invention;Fig. 2, a View in front elevation of said device; Fig. 3, a view invertical longitudinal section thereof; Fig. 4, a plan view of the saiddevice, the die being shown removed.

Referring to the said drawings, the numeral 1 designates the ordinarydie-holder.

2 designates the die.

3 designates the usual key or wedge.

4 is a bar, bolt, or slide placed in the dieholder below the die in achannel 5 so formed as to permit the part 4 to be moved laterally aswell as longitudinally. This lateral move ment is necessary to permitthe die to be taken from the holder, as will soon be easily perceived.The bar, bolt, or slide 4 I connect with the die, preferably by a pin 6,which is rigidly secured to the part 4 and loosely entered inthe die. Itis apparent that for convenience and cheapness in the construction ofthe parts 2, 4, and 6 they should be separately formed, but notessentially so. The

Serial No. 711,295. (N0 model.)

bar, bolt, or slide 4 is threaded at each end, as at 7, and provided oneach threaded portion with a nut 8. Washers which I preferably interposebetween the said nuts and the die-holder are designated by the numerals.By manipulating the said nuts the die can be adjusted or lockedagainstlongitudinal movement. By manipulating either one of the saidnuts when the other is loosened the die can be moved or locked againstlongitudinal movement.

Having, as I believe, sufficiently describedmy invention, I will nowproceed to state what I think is new and desire to secure by LettersPatent. I claim as patentable and desire to cover- 1. The combination ofa die-holder, a die,

and a laterally and longitudinally movable bar in said die-holder andconnected with said die, whereby the die can be moved in said holder,substantially as described.

2. The combination of a die-holder, a die, a laterally andlongitudinally movable bar in said die-holder and connected with saiddie, whereby the die can be-moved in said holder, and screw means formoving said bar, substantially as described.

3. The combination of a die-holder, a die, a longitudinally-movable barconnected with the said die, in said holder and projecting beyond thedie at opposite sides or ends thereof, whereby the die can behorizontally moved in two directions in said holder, said bar providedwith a threaded portion and a threaded nut loosely placed thereon, bymanipulating which said nut the said bar can be moved, and meansindependent of said bar whereby the die can be locked in said holder,substantially as described.

4. The combination of a die-holder, a die, a longitudinally movable barin said dieholder, whereby the die can be moved, a pin connectionbetween the die and bar, and means independent of said bar whereby thedie can be locked in the die-holder, substantially as described.

5. The combination of a die-holder, a die, a longitudinally-movable barwhereby the die can be moved, a pin connection between the die and bar,and screw means for moving the bar, substantially as described.

6. The combination of a die-holder, a die,

a longitudinally-movable bar whereby the die can be moved, a pinconnection between the die and bar, screw means for moving the bar, andmeans independent of the bar for looking the die in its holder,substantially as described.

7. The combination of the die-holder having the chamber which containsand permits the bar to be moved longitudinally, the die, the bar, thepin connection between the die and bar, and a threaded nut on the bar,whereby it can be moved, substantially as described.

8. The combination of a die-holder, a die, a longitudinally-movable barconnected with the said die and in said die-holder, whereby the die canbe moved, or held against movement, in two directions in said holder,the said die having a dovetail portion, as shown, the said die-holderhaving a dovetailed chamber adapted to receive the said portion. of thesaid die, as shown, a key or wedge, as shown, whereby the die can belocked in said holder, and screw means for moving or looking the saidbar against movement, substantially as set forth.

In testimony that I claim the foregoing I have here signed my name, inthe presence of two subscribing witnesses, this 27th day of March, 1899.

GEORGE XV. BLAKESLEE.
